Hi Sellam I don't see what is obvious about it. When doing math in school, I always wrote i + 1 = i, which I new was false unless i happened to be infinity. Things like i + 1 =: i or i + 1 -> i make much more sense. This typical high level language format makes reading code confusing. Sometimes one reads left to right for operations while others, one has to look to the right to find the sequence and then look to the left to complete. In this simple example, there is little chance of errors but those times I've debugged errors in others code, it has often been the order of execution that somehow got messed up. Most Forth's have the concept of a VALUE that can be used as a variable. Still, = is a question not an operation. All action progresses left to right, top to bottom. Reading code for an experienced person, when good names for words are chosen, is like reading instructions for how to complete the action. I know of one case that an upper management person sent code back to the programmer and said that he must have made a mistake. It looked like he'd sent the specification for the code and not the actual program. You know you are doing the right thing with this kind of compliment. I doubt one would ever see that happen when coding in C. Dwight
